Abstract
Description
Die Erfindung bezieht sich auf eine Fahrzeugbremsanlage mit einem elektromechanischen Bremskraftverstärker und einem Schlupfregelsystem.The The invention relates to a vehicle brake system with an electromechanical brake booster and a slip control system.
Eine
derartige Fahrzeugbremsanlage ist beispielsweise aus der
Aufgrund der Massenträgheiten des elektromechanischen Bremskraftverstärkers sind bei einem Regeleingriff des Antiblockiersystems auftretende Pulsationen des Bremsdrucks in der Hydraulikeinheit am Bremspedal kaum oder nicht mehr spürbar. Für den Fahrer ist daher schwer zu erkennen, ob in einer möglicherweise stabilitätskritischen Fahrsituation das Antiblockiersystem anspricht oder nicht, da für diesen die haptische Rückmeldung am Bremspedal fehlt. Damit aber fehlt dem Fahrer die Möglichkeit, aus kritischen Fahrsituationen zu lernen und sein Verhalten anzupassen.by virtue of the inertia of the electro-mechanical brake booster are pulsations occurring during a control intervention of the anti-lock braking system the brake pressure in the hydraulic unit on the brake pedal hardly or no longer noticeable. For the driver is therefore difficult to recognize whether in a possibly stability critical Driving situation, the anti-lock system responds or not, because for this the haptic feedback on the brake pedal is missing. But with that the driver lacks the possibility of critical driving situations to learn and adapt his behavior.
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen. Insbesondere zielt die Erfindung darauf ab, eine Fahrzeugbremsanlage der eingangs genannten Art zu schaffen, bei der ein Bremskrafteingriff durch das Schlupfregelsystem dem Fahrer am Bremspedal haptisch angezeigt wird.Of the Invention is based on the object to remedy this situation. In particular, the invention aims to provide a vehicle brake system of the type mentioned above, in which a brake force intervention indicated by the slip control system haptic to the driver on the brake pedal becomes.
Diese Aufgabe wird durch eine Fahrzeugbremsanlage gemäß Patentanspruch 1 gelöst. Die erfindungsgemäße Fahrzeugbremsanlage zeichnet sich insbesondere dadurch aus, dass bei einem Bremskrafteingriff durch das Schlupfregelsystem der Elektromotor des elektromechanischen Bremskraftverstärkers derart angesteuert wird, dass ein vibrationsartiges Motormoment erzeugt wird.These Task is achieved by a vehicle brake system according to claim 1 solved. The vehicle brake system according to the invention is characterized in particular by the fact that at a brake force intervention by the slip control system the electric motor of the electromechanical Brake booster is driven such that a vibration-like engine torque is generated.
Das Erzeugen einer solchen künstlichen Vibration über den Elektromotor des Bremskraftverstärkers, über die dem Fahrer ein Bremskrafteingriffs fühlbar anzeigt werden kann, lässt sich ohne großen zusätzlichen Aufwand realisieren. Insbesondere sind hierbei keine Eingriffe in die Hardware der Bremsanlage erforderlich.The Generating such artificial vibration via the electric motor of the brake booster, over which noticeably indicates to the driver a brake force intervention can be, can be without much additional Realize effort. In particular, here are no interference in the hardware of the brake system required.
Versuche haben gezeigt, dass die Frequenz des Vibrationsanteils des Motormoments vorzugsweise im Bereich von 2 bis 50 Hz liegen sollte und eine Amplitude im Bereich von 0,5 bis 2 Nm aufweisen sollte.tries have shown that the frequency of the vibration component of the engine torque preferably should be in the range of 2 to 50 Hz and an amplitude should be in the range of 0.5 to 2 Nm.
Weiterhin ist es denkbar, über unterschiedliche Frequenzen und/oder Amplituden unterschiedliche Arten von Bremskrafteingriffen zu identifizieren.Farther It is conceivable, over different frequencies and / or Amplitudes to identify different types of braking force interventions.
Weitere, vorteilhafte Ausgestaltungen sind in den Patentansprüchen angegeben.Further, advantageous embodiments are in the claims specified.
Nachfolgend wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Die Zeichnung zeigt ein:following the invention will be described with reference to embodiments shown in the drawings explained in more detail. The drawing shows:
